Abstract
During preparation for migration of a logical volume from a source data storage appliance to a destination data storage appliance, a determination is made as to whether at least one host that accesses a copy of the logical volume contained in the source data storage appliance is managed by a host administration server. In response to determining that at least one host that accesses the copy of the logical volume contained in the source data storage appliance is managed by the administration server, a rescan request is transmitted to the administration server. The rescan request causes the host administration server to instruct each host that is managed by the host administration server that accesses the copy of the logical volume contained in the source data storage appliance to perform a rescan operation to discover at least one new path to the logical volume.
